摘要： The present invention relates to cross-linked polymers absorbing aqueous liquids, which are built up of partially neutralized, mono-ethylenically unsaturated, acid groups-containing monomers, optionally further monomers copolymerizable with these, as well as optional polymers suitable as a graft basis, and that can be produced by using cross-linking agents of polyunsaturated amino alcohols. The used cross-linking agents are reaction products of (meth)allylamines with monoglycidyl compounds, di-, tri- or tetraglycidyl compounds, and optional alkylene oxide; reaction products of (meth)allylamines or saturated primary amines with (meth)acrylglycide esters and/or (meth)allyl glycidyl ethers and optional alkylene oxide; as well as reaction products of di- and polyamides with (meth)allyl glycide esters and/or (meth)acrylglycide esters and optional alkylene oxide. The polymers according to the present invention provide superabsorbers whose property level meets the practice-oriented requirements with respect to retention, absorption under pressure, swelling pressure, and permeability for aqueous liquids. Such polymers are used as absorbents for water and aqueous liquids in constructions for the absorption or body fluids, in current-conducting and light-transmitting cables, and in the cultivation of plants.

摘要： The present invention relates to a process for producing water-absorbing sheet-like materials which consist of a water-absorbent polymer and a prefabricated nonwoven fabric, wherein the prefabricated nonwoven fabric is impregnated with a solution comprising partially neutralized acrylic acid and at least one cross-linking agent and is squeezed to a certain coating amount, and the monomer solution thus applied is characterized in that the polymerization is carried out in the presence of radical initiators which cannot be activated thermally and at least one thermally activatable radical former used in addition. The additional use of a thermally activatable radical former in the polymerization results in products having a low residual monomer content, an improved water absorption under load, and a higher retention, with a production method being employed which is technically simple and economically efficient at the same time. The thermally activatable initiator portion may either be added to the monomer solution or applied to the substrate in an amount of 0.01 to 0.5 mole percent, relative to the monomer to be polymerized.
